Thermite can be ignited in a couple of different ways.First, the Mg ribbon can be ignited using a bunsen burner flame. The ribbon can then be dropped into the flower pot, igniting the thermite.Second, the Mg ribbon can be inserted into the powder like a fuse, then lit with the bunsen burner.
Chemical reactions
A thermite reaction using iron (III) oxide. The sparks flying outwards are globules of molten iron trailing smoke in their wake.
History
The thermite ( thermit) reaction was discovered in 1893 and patented in 1895 by German chemist Hans Goldschmidt. Consequently, the reaction is sometimes called the "Goldschmidt reaction" or "Goldschmidt process".
Types
Red iron (III) oxide (Fe 2 O 3, commonly known as rust) is the most common iron oxide used in thermite. Magnetite also works. Other oxides are occasionally used, such as MnO2 in manganese thermite, Cr2O3 in chromium thermite, or copper (II) oxide in copper thermite, but only for specialized purposes.
Ignition
Metals are capable of burning under the right conditions, similar to the combustion process of wood or gasoline. In fact, rust is the result of oxidation of steel or iron at very slow rates. A thermite reaction is a process in which the correct mixture of metallic fuels are combined and ignited. Ignition itself requires extremely high temperatures.
Civilian uses
Thermite reaction proceeding for a railway welding. Shortly after this, the liquid iron flows into the mould around the rail gap
Military uses
Thermite hand grenades and charges are typically used by armed forces in both an anti- materiel role and in the partial destruction of equipment; the latter being common when time is not available for safer or more thorough methods.
Hazards
Thermite usage is hazardous due to the extremely high temperatures produced and the extreme difficulty in smothering a reaction once initiated. Small streams of molten iron released in the reaction can travel considerable distances and may melt through metal containers, igniting their contents (see images).
Why is thermite used in war?
Thermite has long been used by the military for the destruction of war material, when it becomes necessary to abandon a position.
What is thermite made of?
We’re going to make thermite out of iron oxide and aluminum; both because these are the most common materials used and because in a post-disaster scenario, those are the materials you are most likely to encounter. You can get iron oxide by scraping rust off of whatever steel or iron objects you can find and you can get aluminum powder by filing a piece of aluminum. The one material that will not be commonly available, which you will need, is the magnesium tape. Fortunately for us, that’s relatively inexpensive, doesn’t take up much room and is readily available from online retailers, like eBay and Amazon.
How to keep thermite from spilling out of a loom?
Have an assistant pour the powder into the funnel, while you move the loom around, shaking the powder down to fill it. When the loom is filled, tape the end, as well as taping around the loom periodically, to keep the thermite from spilling out.
What temperature does thermite burn?
Developed by a German chemist in 1893 to weld train tracks together, thermite burns at over 4,000°F (2204°C). That’s enough to cut through steel, which has a melting point of 2750°F (1510°C). Igniting something that burns this hot is difficult, requiring a temperature of over 3,000°F (1649°C) to autoignite.
